Cardiology

Outpatient healthcare services are provided in Cardiology Unit of the Türkiye Hospital  from 08.30 to 17.30 every weekday, except Saturday and Sunday.

Healthcare services provided by our physicians and other personnel are supported by high technology modern devices in our cardiology unit.

Based on diagnostic and therapeutic modalities available, substantial information can be obtained about the condition of heart using painless methods that do not require intravenous catheterization or administering contrast agent, and the procedure is not associated with the risk of vascular injury or tissue damage.  Mainly, following methods are used in this area:

  • Electrocardiogram (ECG),
  • Stress test ECG,
  • Holter monitor ECG and
  • Color Doppler echocardiography


ECG (Electrocardiogram)
Electrocardiography device is used to record the electrical signals produced by hearth tissue by means of electrodes attached on arms, legs, and chest.

Heart rate and conduction disorders can be identified, and coronary failure and infarction can be diagnosed; hypertrophies of heart wall and ventricular dilatation can be determined; functions of electronic pacemaker can be evaluated, and effects of certain heart medicines, electrolyte imbalance (especially serum potassium deficiency or excess) and effects of non-cardiac diseases on the heart can be explored with ECG.

ECG is used as a laboratory method.  ECG data should be correlated with patient’s complaints, examination findings and other laboratory findings.

Treadmill Exercise Test
Some ECG changes may not be recorded while patient is resting, but they can be manifested by increasing heart rate by physical exercise. In order to determine such exercise-induced changes, “treadmill exercise test” is used.

Taking the test, the individual walks and runs on a moving belt, of which speed and incline are set according to a certain protocol.   At appropriate times prior to and during testing and at rest, ECG traces and blood pressure are recorded.

With the exercise testing, it is possible to determine whether the chest pain is a result of coronary failure, and if the patient with no chest pain has silent coronary failure and also to determine exercise capacity or safe level of exercise as well as heart rate and blood pressure responses to exercise and heart rate disorders during the exercise, and outcomes of the treatment are assessed. In addition, this method is also applied to evaluate the patients, who has risk factors of coronary artery disease, and to monitor the patients with coronary failure and with infarction, who had by-pass surgery, and patients who underwent balloon angioplasty.

Holter Monitor (ECG)
"Holter Monitor (ECG)" is among modalities, which are used to obtained specific cardiac data.

This method involves recording ECG tracing continuously for 24-hours with a device, which is attached to waist belt of the patient. The patient writes daily activities, such as walking, running, driving vehicle, working, eating and sex, and complaints, such as fainting, syncope, palpitation and chest pain, on a diary throughout recording period. The printed Holter records are assessed to identify if an electrocardiographic abnormality developed; if any abnormal trace is found, physician strives to relate the abnormality with complaints and daily activities. Moreover, this method is used not only for evaluating response of patient to medications, electronic pacemaker or other modalities, which are used for treatment of rhythm disorders, but also clarifying outcomes of coronary by-pass surgery and balloon angioplasty. It is recognized as an important method to monitor patients, who has coronary artery disease or is experiencing myocardial infarction.

Holter Monitor (ECG) is preferred for patients, who are not eligible for Treadmill exercise due to high risk or are physically disabled. Recent advanced in computer technology further enhanced diagnostic significance of Holter Monitor (ECG).

Echocardiography
Echocardiography is recognized as elite and first-priority method, which is recently used for making diagnosis of many cardiac diseases. Echocardiographic examination is based on use of high-frequency sound waves, resulting with no risk for the patient. Sound waves are generated by a crystal, which vibrates when an electric current is applied, and a small portion of sound waves is reflected by contact surfaces of cardiac tissues, which have different densities, or erythrocytes. Each point of monitor image shows the electrical current, which is generated by the crystal while reflected sound waves interact with the crystal.

Echocardiography enables physician to measure dimensions and wall thickness of heart, evaluate cardiac contractions, image heart valves, inter-ventricular and inter-atrial septum, vessels originating from heart and lesions and tumors of heart as well as pericardial effusion (fluid collection in pericardium); it is also possible to investigate stenosis, failure and other abnormalities of heart valves and real-time status of prosthetic valves and to measure intra-cardiac blood flow rate and pressure.

Ambulatory Blood Pressure Monitoring
A lightweight monitor is carried with a belt attached on waist of the patient for measuring blood pressure. The monitor inflates the cuff, wrapped around arm, at regular intervals (usually once in 15-30 minutes during daytime, and once in 30-60 minutes along the night) in order to measure the blood pressure and record the results. The device also eliminates the erroneous measurements and calculates the daytime and night averages of blood pressure values, that are fit for evaluation, round the clock. The device is taken from the patient following 24-hour interval and the data saved by the device is reviewed.  Some patients feels anxiety, irrespective of they are aware or not, when they seek medical attention at the hospital or physician's office, and accordingly, blood pressure may be above normal limits, while physician or other healthcare staff is measuring the blood pressure.

This phenomenon is called “white coat hypertension” and may cause incorrect diagnosis of hypertension and unnecessary and even harmful treatments for the patient.  For this reason, “ambulatory blood pressure monitor” is required to eliminate "white coat hypertension" in patients, who has high blood pressure which is not associated with hypertension-emergent disorders, such as heart, eye, and brain.

This method is also useful for assessing the patients with drug-resistant hypertension, patients whose blood pressure decreases below the normal limits secondary to medications,  for patients suffering from hypertensive attacks or patients who require assessment of blood pressure during sleep.
